Coal Boiler Furnace Tube Leak Detection System
Our coal boiler furnace tube leak detection system provides continuous, non‑intrusive monitoring of tube integrity in high‑temperature boiler environments. Designed for power‑generation plants, industrial heating facilities, and large‑scale coal‑fired units, the solution delivers early‑stage leak identification, reducing unplanned shutdowns and minimizing costly water‑hammer or steam‑loss incidents.
How It Works – Real‑Time Acoustic‑Ultrasonic Sensing
The system combines high‑sensitivity acoustic transducers with ultrasonic pulse‑echo technology. Sensors are mounted externally on the furnace tube bundle; they capture the characteristic sound signature of escaping steam or water vapor. Proprietary signal‑processing algorithms filter out boiler noise, temperature‑induced vibrations, and combustion turbulence, isolating true leak events with a false‑alarm rate below 2 %.
Data is transmitted over shielded industrial Ethernet to a PLC‑compatible HMI, where alarm thresholds, trend logs, and predictive maintenance alerts are displayed. Integration follows standard OPC‑UA or Modbus‑TCP protocols, allowing seamless inclusion in existing DCS or SCADA environments.

Application Scenarios
- Base‑load coal‑fired power stations – continuous monitoring of 30‑tube bundles up to 400 MW.
- Industrial steam generators for chemical or paper mills – detection of micro‑leaks that cause water‑hammer in high‑pressure loops.
- Retrofit projects – non‑contact sensor heads can be installed during scheduled outages without boiler disassembly.
- Remote or off‑grid plants – solar‑powered variants support low‑maintenance operations.
Competitive Advantages
Reliability in extreme conditions. All components are rated for sustained exposure to high‑temperature flue gases and corrosive environments, eliminating the need for frequent recalibration.
Reduced downtime. Early leak alerts allow maintenance teams to schedule tube replacement during planned outages, cutting unplanned shutdowns by up to 30 % in comparable installations.
Scalable architecture. The modular sensor layout supports expansion from single‑tube monitoring to full‑plant coverage without additional software licensing.
Compliance. The system complies with IEC 61508 functional safety standards and meets the requirements of major coal‑boiler manufacturers.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for a custom‑engineered coal boiler furnace tube leak detection system?
We accept single‑unit orders for pilot projects, but standard production runs start at 5 units to optimize component sourcing and testing.
Can the system be integrated with existing SCADA platforms?
Yes. The solution offers native OPC‑UA and Modbus‑TCP interfaces, allowing direct data exchange with most commercial SCADA and DCS packages.
What is the typical lead time from order to shipment?
Standard configurations ship within 30 days after purchase order confirmation. Custom sensor housings or special certifications may extend lead time to 45 days.
What warranty and after‑sales support are provided?
All units carry a 24‑month warranty covering parts and workmanship. Our technical team provides 24/7 remote assistance and on‑site service contracts upon request.
